On July 4th, 2012, one of physics' most exhilarating results was announced: a new particle – and very likely a new kind of particle – had been discovered at the Large Hadron Collider, the huge particle accelerator designed to reproduce energies present in the universe a fraction of a second after the Big Bang. The particle's existence had been speculated on for nearly fifty years: here, finally, was proof. Professor Lisa Randall of Harvard University is one of the world's most influential theoretical physicists, and author of the bestselling Knocking on Heaven's Door and Warped Passages. In Higgs Discovery she deftly explains both this epochal discovery and it's startlingly beautiful implications.
The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the Universe? Did the discovery announced on 4 July 2012 finish the search? And was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our Universe. Little wonder the hunt and discovery of this new particle produced such intense media interest. Here, Jim Baggott explains the science behind the discovery, looking at how the concept of a Higgs field was invented, how the vast experiment was carried out, and its implications on our understanding of all mass in the Universe.
The Higgs mechanism, which is responsible for electroweak symmetry breaking and unitarization of massive W± and Z scattering, is a fundamental ingredient of the Standard Model (SM). However, there is as yet no direct evidence of the Higgs boson, so that the details of the Higgs sector, if it even exists, remain a mystery. Here, we explore several scenarios that alter the Higgs sector from that of the SM. The first uses additional symmetries of the Higgs sector to address certain issues of neutrino ixing, the second uses extra dimensional boundary conditions to avoid the need for a Higgs entirely, and the last uses additional Higgs fields to provide an alternative explanation for tiny neutrino masses.
The Standard Model explains how the universe works at distances a billion times smaller than the size of an atom. However, in the Standard Model, none of the particles have mass, yet one only has to look around to see that things do have mass. Explaining the source of mass has been the goal of particle physicists for over half a century, culminating in the discovery of the Higgs boson at the Large Hadron Collider in 2012. Supporting the Next Generation Science Standards' emphasis on scientific collection and analysis of data and evidence-based theories, this book simplifies the difficult concept of the Higgs mechanism through analogies to everyday experiences as well as pictures, diagrams, and intuitive explanations.
Higgs Force tells the dramatic story of how physicists produced their modern understanding of the Cosmos by unlocking the secrets of matter. Physicists believe that the universe began in a state of perfect symmetry. As the universe expanded and the temperature fell, much of this symmetry was lost in an all-encompassing transformation. We see the results all around us - the evolution of a complex and dynamic universe supporting the existence of sentient life. Deep beneath the Franco-Swiss border, CERN, with the mighty Large Hadron Collider, is seeking the ultimate confirmation of these ideas - the elusive Higgs particle, known to some as the God Particle.
Forty years ago, three physicists - Peter Higgs, Gerard 't Hooft, and James Bjorken - made the spectacular breakthroughs that led to the world's largest experiment, CERN's Large Hadron Collider. Against a backdrop of high politics and billion dollar budgets, this is the story of their work, the quest for the Higgs boson, and its eventual discovery.
The masses of fermions and gauge bosons enter the Standard Model through the Higgs mechanism, which is satisfactory technically but is not understood physically. We do not know what nature really does to give mass to particles, nor what experimental clues will lead us to nature's solution. Understanding Higgs physics is necessary in order to complete the Standard Model, and to learn how to extend it and improve its foundations.This book is a collection of current work and thinking about these questions by active workers. It speculates about what form the answers will take, as well as updates and extends previous books and reviews. Some chapters emphasize theoretical questions, some focus on connections with other areas of physics, and some discuss how we can get the data to uncover nature's solution.
